Title: Integrated fabrication method of forming connectors  through insulative layers

Abstract: AN INTEGRATED FABRICATION METHOD OF FORMING          CONNECTORS THROUGH INSULATIVE LAYERS               Abstract of the Disclosure In integrated circuit fabrication, a method is pro-vided for forming metallic connectors through a layer of electrically insulative material.  The method comprises forming a layer of electrically insulative material on a substrate and then forming a mask of photoresist material having a plurality of openings through which said insula-tive layer is exposed on said insulative layer.  Then, the exposed portions of said insulative layer are removed by etching to form openings through which the underlying substrate is exposed, after which a first metal layer is deposited over the masked substrate.  This metal layer is thinner than the insulative layer so that the openings in the insulative layer are only filled part way up with metal.  Then, the photoresist mask is removed thereby re-moving the metal layer deposited on it to leave only the metal in the insulative layer openings.  Next, a second layer of metal is deposited over the first insulative layer and over the remaining metal in said openings, after which portions of the second metal layer over the insulative layer are removed to form a metallization pattern which is con-tinuous with the metal in said openings.

Abstract: ABSTRACT OF THE DISCLOSURE           A flexible coupling which permits both rotational and axial movement.  An elastomeric member is sandwiched between two coupling members and is held in place in such a manner that the coupling members do not contact each other.  Thus, each of the coupling members includes an elongated portion provided with projections which are received within cavities defined by radially extending fingers formed on the elastomeric member. The couplings are angularly offset 90° with respect to each other. Portions of the elastomeric member are held in compression between ends of the elongated portion and retainers by screw fasteners.  The retainers and the screw fasteners associated with one coupling member do not contact the other coupling member.

Abstract: ABSTRACT            An electrical connector assembly for use with flat flexible cable includes a plurality of electrical contacts each having a planar body portion from which extends a single cantilever arm.  The arm has a pair of spaced apart insulation piercing teeth extending therefrom in a plane arranged at an angle to the plane of the planar body part.  Each electrical contact is mounted in a passageway in a contact block which is accommodated within a housing shell.  A pair of housing members are pivotally mounted to the housing shell and adapted to move from an open position to a closed position.  When moving from the open position to the closed position they cause the teeth of the contacts to pierce the insul-ation of a cable when operatively positioned between the housing members so that the teeth engage between them a conductor of the cable.

Abstract: Abstract An uninflated unmounted tire is supported in a frame of the apparatus for engagement with a sealant applicator head that contacts the interior tire liner after a bead spreading device on the frame spreads apart the tire beads, and an elevator member on the frame raises the tire.  The applicator head has a tire engaging profile corresponding to that of the tire and an elongated opening from which a highly viscous, sticky sealant is discharged onto the tire liner under the tread in a layer of pre-determined cross section as the tire is rotated on the frame past the applicator head.  A complete coating of sealant is applied during one revolution of the tire, with the sealant having a butt joint, or an overlapping splice formed when the elevator member is lowered a predetermined amount by a drop-off mechanism as the tire completes one revolution of sealant application.

Abstract: The invention provides a circuit for converting M-bits of an input data word having M + A bits in addition to an input parity bit, to B-bits of an output data word having B + A bits in addition to an output parity bit.  A code-conversion circuit is responsive to the input M-bits for generating a converted data word having B-bits plus a secondary parity bit which gives the converted data word a parity value the same as that of the input M-bits.  The secondary parity bit is exclusive-ORRED with the input parity bit to produce an output parity bit which renders the parity value of the output data word the same as that of the input data word. - i

A low-resistance semiconductor layer adjoins the first conductivity type semiconductor layer and contains large quantities of impurity of the first con-ductivity type.  A semiconductor layer for light emission adjoins the low-resistance semiconductor layer and has the first conductivity type.  A ditch extends from a surface of the second conductivity type semiconductor layer to surround the p-n junction.

Kashyap Walter Wyslouzil ABSTRACT OF THE DISCLOSURE           The single-sided microwave applicator has a section of a microwave waveguide with an open end for receiving microwave energy and an end which is electrically shorted.  A slot is located in one of the wide sides of the waveguide extending along the center line from the shorted end.  A conductive ridge is mounted within the waveguide extending upward from the other side through the slot.  One end of the ridge is connected to the shorted end of the waveguide, while the other end of the ridge is tapered from a point within the slot.  The slot is generally in the order of 3/4 to 1 inch and at least 2 1/2 inches long, when the operating frequency is 2450 MHz.  Since one end of the waveguide is shorted, standing waves are produced resulting in a non-uniform field having at least one maximum along the length of the slot. The electric field produced is non-radiating and its strength diminishes exponentially above the slot.
